Family-based Wireless Sensor Network Technology, Intelligent Systems

With the appearance of Internet, development of the information, technology and progress of modern Hi-Tech, people's living standard improves enormously, physics space of the room and luxurious equipment are no longer the goals that people pursue, people's life needs more comfortable and more intelligent space. As network being ubiquitous, the automation of the individual household appliances can't totally meet people's demands, the household appliances network becomes the inevitable trend. The concepts, such as intellectual house, networked house, family's network, digital family of intellectual house, digital home, etc. are proposed extensively at home and abroad, more and more new technologies are getting application in family intelligent system one after another.The research of family intelligent of low power consumption, low cost, easy group network, is a multi-disciplinary to cross subjects for research which are relevant to automatically control, computer, communication, etc. This thesis is based on "key technology research of intelligent district system based on TCP/IP protocol" and the results of gateway, WEB server information, study the wireless gathers and transmit integrated technology, and the application in the intelligent family. The thesis adopts low consumption wireless transceiver IP-Link1000 which follows IEEE802.15.4 standard, carries on the node development of wireless sensor network and develops the wireless digital family gateway; And the thesis also studies the temperature and humidity intellectual control algorithm in the room based on digital sensor. Though there is a relevant report of family intelligent system developmental research based on wireless technology, they are not popularized and applied because of its dependability, price, etc. This subject solves family intelligent system and key technology problems, such as reliable, low power consumption, networked, etc. This technology can be used at intelligent house, and applies to industrial applications and environmental monitoring systems based onwireless network control.This thesis is divided into 5 parts. Chapter one introduces the research background and current situation, and has analysised the research contents and key of innovation; Chapter two introduces the overall scheme of the system, the research of topological structure in detail; Chapter three introduced the hardware designs of the system, the Wireless Digital Home Server briefly, and the wireless module IP-Link1000 and interface of the wireless digital house server especially: Finally, introduces the hardware designs of development platform of the wireless module. Chapter four introduces system software designs, including wireless development platform and Wireless Digital Home Server software design, and the terminal node program of electrical home appliances; Chapter five introduces the fuzzy theory, designs a kind of fuzzy controller, and provides its emulation result based on MATLAB. At last, we use the fuzzy controller in temperature and humidity control at home, and analyze the result of the application.This thesis has introduced a kind of wireless module IP-LinklOOO based on ZigBee technology, applied it to the intelligent family, and developed a kind of wireless family intelligent system. The safe and reliable of the standard of 802.15.4, the low costs and working high dependability for a long time of IP-Link1000 module, can meet the modern family's needs much better, and its cost-performance is high.
